FILTER.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed July 25, 1905. Serial No. 271,131.

T 0 all whom, it may concern:

Be it known that I, CLARENCE R. APPLE- GATE, a citizen of the United States, residing at Evansville, county of Vanderburg, and State of Indiana, have invented certain new and useful Improvements in Filters, of which the following is a specification.

This invention relates to filters of the hollow rotary porous-cylinder type, and parfticularly to filter-cleaning mechanism there- The objects of this invention are the provision of an improved filter-bottom for the collection and removal of these diment, thereby obviating the necessity for flushing each time the porous cylinder is cleaned, and the provision of novel cleaning mechanism which will be operated longitudinally of the porous cylinder while the latter is being rotated, all combined in an improved manner, whereby a most satisfactory cleansing of the filter can be obtained. with rapidity and ease.

The invention is set forth in detail in the following specification, and the novel features and combinations thereof are embodied in the appended claims.

In the accompanying drawings, Figure 1 is a verticalsection; Fig. 2, a cross-section on line x as of Fig. 1, and Fig. 3 a detail of the brush-operating pitmen and related parts.

The filter shell or casing 1 has a water-inlet 2 near its top, and its lower portion 3is made conical and provided with a sediment-outlet 4. This conical bottom is very useful, as it forms a receptacle for the settling of the sediment, besides receiving the sediment which may be removed from the hollow porous filtering-cylinder 5 by the action of the brushes 6, and thus the blowing out of the filter when cleansed becomes an unnecessary operation,

. as the sediment will pass off when the outlet 4 is opened.

The filtering-cylinder 5 is secured in any desired manner to the perforated outlet-pipe 7, so as to be adapted to turn therewith. This pipe is stepped in a bearing 8 and thereat provided with bevelgear 9, while its upper end is passed through a gland-bearing 11 and then into a pipe-coupling 10, secured to a bracket surmounting casing 1. Thefilteredwater pipe 12 connects with the coupling 10. Secured on the upper end of pipe 7 is a bevelgear meshing with another bevel-gear 13, while the usual filter-cylinder-turning mechanism is shown at 14.

Extending across the casing 1 above and below the filtering-cylinder are slotted bars 15, which constitute guides for the brushes 6 as they move up and down and also keeping them in proper position lengthwise of the cylinder at all times. Springs 16 constantly draw the brushes toward each other and keep them against the filteringcylinder.

Journaled in bearings 17 on the cross-bar 18, which also carries the step-bearing 8, are short shafts 19 and 20, having bevel-gears 21, meshing with gear 9, while the outer ends of said shafts have pitmen 22, which connect with and support the brushes 6. The brushes where they pass through the slotted guides 15 are provided with slides 23.

On turning the operating means 14 the liltering-cylinder is rotated, and at the same time the brushes 6 are reciprocated up and. down or lengthwise of the cylinder, and this combined movementthe rotation of the filtering-cylinder and the reciprocation of the brushesgives the cylinder a much more ef- 'fectual cleansing than having the brushes or the cylinder stationary, as in earlier constructions known to this art.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a filter, the combination with a porous filtering-cylinder and a cleaning-brush therefor, of means cooperating with the brush and filtering-cylinder whereby relative turning or rotation of the brush and filtering-cylinder continuously in a given direction and relative simultaneous reciprocation or to-andfro movement of said brush and filtering-cylinder may be obtained.

2., In a filter, the combination with a retary porous filtering-cylind er, of a reciprocating brush bearing thereagainst, and means for rotatingsaid cylinder and reciprocating said brush at the same time to cleanse the cylinder.

3. In a filter, the combination with a rotary porous filtering-cylinder and a rotary pipe on which said cylinder is carried, of a reciprocatory brush bearing against said cylinder and gearing and a pitman operatively connecting said brush with the rotary pipe aforesaid, whereby the brush is reciprocated as the cylinder rotates.

4. In a filter, the combination with a porous filtering-cylinder and a rotary pipe on which said cylinder is carried, of a reciproand gearing and pitmen connecting the rotary pipe with the brushes, whereby the brushes are made to reciprocate as the cylinder revolves.

In testimony whereof I hereunto am); my signature in presence of two witnesses.
